Abstract

PURPOSE:To enable to obtain excellent recording even for automatic answering recording, by detecting input signals through a filter circuit, comparing the level with the set level, adjusting the gain control circuit with the maximum input level and operating this circuit via a delay circuit. CONSTITUTION:When an automatic set switch 7 is depressed, a time set circuit 6 is driven and the pulse with predetermined time width is fed to a maximum value storage circuit 5. On the other hand, the signal given to an input terminal 1 is made for amplitude correction according to the frequency with a filter circuit 40, then it is detected at a level detector 4, and the gain of a gain control circuit 3 is controlled with the signal of maximum level in the set time at the maximum value storage circuit 5. The output 2 is output to a recording head 34 via a recording amplifier 33. When a power switch (or timer switch) is on, an automatic recording level set circuit A is operated via a power supply circuit 35, differentiation circuit 36, delay circuit 41, switching element 38 and switch 37, enabling excellent recording even for automatic answering recording.
